I'm unable to adjust the screen brightness on my Yoga 920. It's stuck. The F11 and F12 keys do nothing.
I have updated the BIOS. I have reinstalled the driver. When I do so, it fixes the problem ... until the next time the laptop goes to sleep or shuts down. Then, when it comes back on, the brightness is stuck at wherever it was before.
If I then reinstall the driver *again*, it fixes the problem ... until the next sleep/shutdown, when the problem reappears.
A Lenovo support agent told me the only thing to do is a hard reset on the machine, restoring it to factory condition. Obviously I'd rather not deal with that hassle if there's a less destructive way to fix the problem.

I have the same issue and this is so frustrating! I found this article but I'm unable to manually update the intel drivers. Which version of the driver do you have?
I have 220.127.116.1173 while the lastest on the intel website are Version: 18.104.22.16818
Please let me know if you find a solution
